Abstract
A method and system for probing FCode in problem state memory. A PCI device is detected from a PCI-PCI bridge node included in a device tree. A child node for the detected PCI device is created in problem state memory. The active package is switched to the child node, and the processor switches from running in privileged mode to running in problem mode. FCode of an FCode driver in the PCI device is probed. Data, properties and methods generated in response to the probe are created in problem state memory. After the probe is complete, the active package is switched to the parent node of the child node, and the processor switches back to running in privileged mode.
